Air quality today

The air quality in Hartberg, Styria, Austria is currently rated as Good. According to the latest assessment, the dominant pollutant is PM10, with a reported reference concentration of 27.96 micrograms per cubic metre. Measurements for PM2.5 are not available. This evaluation is based on three valid observations collected for the area. The reference value serves as the benchmark for evaluating ambient concentrations.

The figures are presented through the OpenAQ platform, which aggregates air‑quality data from participating monitoring stations. No additional context such as trends or forecasts is included in this summary. The snapshot reflects conditions at the time of measurement without implying changes over time. This page is informational; for health guidance, use official sources such as EPA AirNow or WHO.

What the data includes

The dataset for Hartberg in Styria contains measurements for five pollutants – nitrogen monoxide (NO), nitrogen dioxide (NO2), ozone (O3), particulate matter 10 µm or less (PM10) and sulphur dioxide (SO2). All values come from a single monitoring site, Hartberg Zentrum, and the record comprises nine individual rows. Three of those rows were refreshed within the last three days, while the remaining six are classified as older data. The most recent timestamps are from 2026‑02‑10 20:00 UTC for NO2, O3 and PM10; the SO2 reading dates back to 2024‑01‑31 08:00 UTC and the NO measurement to 2024‑03‑11 12:00 UTC.

Across the recent data, NO2 varies from about 11.9 µg/m³ at its lowest to 46 µg/m³ at its highest, with a median of roughly 29 µg/m³ and a 10th‑percentile near 15 µg/m³, indicating a fairly wide spread. Ozone shows a tighter band, ranging from 21.7 µg/m³ to 28 µg/m³, median 24.9 µg/m³, and 10th‑percentile around 22.3 µg/m³. PM10 values sit between 19 µg/m³ and 27.96 µg/m³, median 23.5 µg/m³, with the lower decile close to 19.9 µg/m³. Sulphur dioxide, recorded only in older data, spans 2 µg/m³ to 3.24 µg/m³, median about 2.62 µg/m³. NO is represented by a single older measurement of 1.38 µg/m³.

Because most rows are older and only one monitoring location supplies the data, the snapshot does not capture spatial or temporal variations that may occur across Hartberg. Consequently, while the figures give a concrete picture of recent pollutant levels at the central site, conditions elsewhere in the city or at different times could differ.
